Subject: [PATCH 08/24] tests/qtest: Add test for Aspeed HACE
Date: Wed,  7 Apr 2021 19:16:21 +0200
Message-ID: <20210407171637.777743-9-clg@kaod.org> (raw)
In-Reply-To: <20210407171637.777743-1-clg@kaod.org>

From: Joel Stanley <joel@jms.id.au>

This adds a test for the Aspeed Hash and Crypto (HACE) engine. It tests
the currently implemented behavior of the hash functionality.

The tests are similar, but are cut/pasted instead of broken out into a
common function so the assert machinery produces useful output when a
test fails.
